+`render` can return any valid React node. This includes React elements such as `<div />`, strings, numbers, [portals](/reference/react-dom/createPortal), empty nodes (`null`, `undefined`, `true`, and `false`), arrays, and other [iterables](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Iteration_protocols#the_iterable_protocol) of React nodes.
 
 #### Caveats {/*render-caveats*/}
 
 - `render` should be written as a pure function of props, state, and context. It should not have side effects.
 
+- If you return an iterable from `render`, avoid one-shot iterators that can only be enumerated once. React may enumerate the returned value more than once, so prefer arrays or iterable objects that create a fresh iterator each time.
+
 - `render` will not get called if [`shouldComponentUpdate`](#shouldcomponentupdate) is defined and returns `false`.
 
 - When [Strict Mode](/reference/react/StrictMode) is on, React will call `render` twice in development and then throw away one of the results. This helps you notice the accidental side effects that need to be moved out of the `render` method.
